I had to disassemble most of the DSH since in my version all the cables were running through the left side of the DSH unlike on most of the pictures I could find on the web.
Still need to install the enclosure.
The printer is working and the z-tilt is a nice feature.
However, something is still not right with my built (pre-assembled) as I still have a 0.45 mm difference in height of the MIC-6 bed… before the upgrade it was about 1.5mm!
Frame is more sturdy than before. It’s now almost perfect at right angles. I can close the enclosure door.
As a result of the new top frame and platform frame, the platform is now leveled as it should be.
The automatic bed-tilt is working like a charm. Difference between corners is consistently < 0.05 mm.
Don’t know why, but the printer is much more quiet than before.
What I had to adjust or improve
- Changed config to
to fit my needs and my customized heat-sink fans (2x4010 Noctua) => custom [homing_override]
stealthchop_threshold: 999999 for the x and y steppers.
customized START_PRINT and END_PRINT macros due to bugs.
- I had to disassemble the DSH in order to properly manage the cables. In my version, the cables were all running from the right side of the DSH and also being stuck at the back of the DSK, making it impossible to use the new cable holder.
- Cut the top frame in order not to disassemble the DSH a second time to complete the build.
- Added a piece of cable chain to support the print head cable sleeve as it was touching the print bed depending of the position.
- Reused the cable holder from the old platform to maintain the heat bed cables in place.
What is not working
Despite the new frame and the bed leveling, the first layer is not how it should be. For troubleshooting, I have enabled the bed mesh in Klipper. The result is shown below :
Even with bed mesh enabled during the print, the first layer was still crashing into the bed. Considering the printer is equipped with the MIC-6 bed, it is unlikely the bed is bent as shown above. Therefore, the hypothesis I have is that the bed is actually close to flat, but the gantry is bent in both x and y directions. To verify this, I have adjusted the T0 and T1 macros with a BED_MESH_OFFSET to account for the difference of where the dsh is attached on the gantry and the position of the probe.With this setup I could finally get a satisfactory 1st layer. It is likely my printer was damaged during the transport...
I would be curious to know if anyone else had similar issues.
90% completed :-)
